Problems solved by technology

[0004] In order to solve the defects of poor sealing performance, high maintenance cost, and failure to return automatically after pressure relief in the prior art, the present invention provides a torsion spring gravity valve with simple structure, good sealing performance and automatic return after pressure relief. The type explosion-proof door is an improvement on the basis of the traditional...

Abstract

The invention provides a gravity type explosion door with a torsion spring so as to overcome the defects that a gravity type explosion door is poor in airtightness, cannot be automatically reset afterpressure relief and excessively relies on the weight of a protective cover, so that materials are wasted, and the gravity type explosion door is too cumbersome. The gravity type explosion door with the torsion spring is characterized in that the gravity type explosion door comprises a flange plate, the torsion spring and a protective cover; the flange plate is fixedly mounted on a sleeve at the tail of a boiler and connected with the explosion door protective cover through the torsion spring; an outlet of the explosion door is obliquely formed and covered with the protective cover; and a groove formed in the edge of the flange plate is matched with a protrusion of the edge of the protective cover, and the protrusion of the edge of the protective cover is made of a high-temperature-resistant elastic material.

Example Embodiment

[0010] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0011] See figure 1 , figure 2 A torsion spring gravity type explosion-proof door includes a flange plate, a torsion spring, and a protective cover. The flange plate is fixedly installed on the sleeve at the tail of the boiler and connected with the explosion-proof door protective cover by a torsion spring. The outlet is inclined and covered with a protective cover, the flange plate edge is provided with a groove corresponding to the edge protrusion of the protective cover, and the edge protrusion of the protective cover is polytetrafluoroethylene.
